Messi and Ronaldo take enduring rivalry to record sixth World Cup

Dec 2 : Two adjacent transparent bins in London became the venue for a silent but heated debate in 2015, with smokers depositing their stubbed-out butts to settle a burning question: who was the best soccer player in the world, Lionel Messi or Cristiano Ronaldo?
